When Nick is examining the semi-automatic handgun on the tram, he pulls out the magazine and says two rounds were fired. Unlike a revolver, it is not possible to determine how many rounds have been fired just by looking at how many rounds are in the magazine. The magazine may hold 15 rounds, but there may only have been 1 to 14 loaded.
